Pollination 47 



row soon and care must be taken to prevent the plants 

 from becoming so thick that they cannot do well. The 

 cultivator must be kept running close to keep the row 

 from getting too wide. Thinning out the plants left may 

 also be necessary at times. 



Partial shade, especially in the hot, dry climates of the 

 West, is an advantage to these fruits. This is not easy 

 to secure without injury from the roots of the trees which 

 produce it. In the home-garden it may be feasible to do 

 this at times. It may also prove desirable to plant among 

 trees in the home-garden, even though the results are not 

 as good as in the open. If land is limited this will make 

 it possible to utilize it to better advantage. It may also 

 insure better tillage for the trees than they might other- 

 wise secure. 



POLLINATION 



The need of planting different varieties together to 

 insure proper fecundation of the blossoms is a recognized 

 factor in orchard planting. A similar need of interpol- 

 lination is sometimes evident among bush-fruits. A 

 number of varieties, both of red raspberries and black- 

 berries, appear to be partially sterile when planted alone. 

 The Cuthbert, our most satisfactory commercial variety, 

 bears an abundance of pollen and is apparently fully self- 

 fertile. Its blossoming season is also long; it is therefore 

 an excellent sort to plant with other reds. It is al- 

 ways safe to plant different varieties of the same fruit 

 near together. Nothing will be lost and much may be 

 gained.
